5 2017 Ambient Air Plan.docx 5/23/2017 Introduction In October 2006, the United States Environmental Protection Agency (EPA) issued final Federal Regulations (40 CFR Part 58) concerning state and local agency ambient air monitoring networks. These regulations require states to submit an annual monitoring network review to EPA. This document provides the framework for establishment and maintenance of Alabama s air quality surveillance system, lists changes that occurred during 2016, and changes proposed to take place to the current ambient air monitoring network during 2017/2018. Public Review and Comment The annual monitoring network review must be made available for public inspection for thirty (30) days prior to submission to EPA. For 2017, this document was placed on ADEM s website on 05/23/2017 to begin a 30-day public review period. This document can be accessed at the following link: Or by contacting: Michael E. Malaier, Chief Air Assessment Unit Field Operations Division Alabama Department of Environmental Management P.O.

6 2017 Ambient Air Plan.docx 5/23/2017 Overview of Alabama s Air Monitoring Network Ambient air monitors in the state of Alabama are operated for a variety of monitoring objectives. These objectives include determining whether areas of the state meet the National Ambient Air Quality Standards (NAAQS), to provide public information such as participation in EPA's AirNow program, Air Quality Index (AQI) reporting for larger Metropolitan Statistical Areas (MSAs), for use in Air Quality models and to provide data to Air Quality Researchers. Alabama monitors the six (6) criteria pollutants which have NAAQS identified for them: Carbon Monoxide (CO), Lead (Pb), Nitrogen Dioxide (NO2), Ozone (O3), particulate matter (PM10, PM2.5, and PM10-2.5), and Sulfur Dioxide (SO2). There are other non-criteria pollutants, such as PM2.5 speciated compounds, that are also monitored for special purposes. In addition, meteorological data is also collected to support the monitoring and aid in analysis of the ambient air monitoring data. In Alabama, the air quality surveillance system is operated by the state environmental agency, the Alabama Department of Environmental Management (ADEM), and two local agencies, the Jefferson County Department of Health (JCDH), and the Huntsville Department of Natural Resources and Environmental Management (HDNREM). Each agency has performed the required annual review of their portion of the current ambient air quality network and developed a proposed network plan to be implemented during This document is a compilation of reports from each agency. An overview of the 2017 Alabama Monitoring Network can be seen in Table 1. Currently, the Air Quality Index (AQI) is reported for Huntsville, Birmingham, Mobile, Montgomery and Phenix City on the Internet at the sites listed below. ADEM JCDH HDNREM Page 6 of 215

7 2017 Ambient Air Plan.docx 5/23/2017 Summary of findings of the network review ADEM Summary of changes in ADEM in 2016/2017 Wetumpka, ADEM (AQS ID ) ozone monitoring site had to be moved due to loss of access to the site. In consultation with EPA, the site was moved to 206 Queen Ann Road, Wetumpka, Alabama and assigned AQS ID Monitoring began March 17, Phenix City-Downtown, ADEM (AQS ID ) particulate matter monitoring site, located behind St. Patrick s Church, had to be moved to th Avenue in January 2016 due to loss of access to the site. The lease for the th Avenue location was not renewed and operations ceased at the end of September In consultation with EPA, the particulate matter monitoring site has been relocated to South Girard School and assigned AQS ID Monitoring began January 18, Lhoist (AQS ID ) SO2 DRR monitoring site was added to Alabama s Air Network. Monitoring began January 1, Summary of proposed changes for ADEM in 2017/2018 The Phenix City-Ladonia ozone site (AQS ID ) will be shut down at the end of the 2017 Ozone season. In 2018, all ambient air monitoring activities in the Phenix City area will be consolidated to the South Girard School (AQS ID ) monitoring site. The Phenix City-South Girard School site is expected to be completed during the summer of 2017 and will concurrently monitor ozone until the end of the season. The South Girard School (AQS ID ) ozone will replace the Phenix City-Ladonia ozone site (AQS ID ) beginning in March ADEM proposes to close the PM2.5 monitor at the Childersburg site (AQS ID ) due to its low design value and since it is not in an MSA. This site is not required by 40 CFR 58, Appendix D. ADEM plans to begin monitoring SO2 at the Ward site in Sumter County (AQS ID ) as a background site. The monitor will be designated as a Special Purpose Monitor (SPM). HDNREM No changes were made in 2016 and no changes are planned for the Huntsville Air Monitoring Network. JCDH Summary of changes for JCDH in 2016/2017 Replacement of shelter at Shuttlesworth Addition of PM2.5 continuous monitor at Shuttlesworth Discontinued monitoring for Low Vol PM10 at Tarrant, Fairfield, Sloss Shuttlesworth and McAdory.

10 2017 Ambient Air Plan.docx 5/23/2017 Network Plan Description As per 40 CFR Part 58.10, an annual monitoring network plan which provides for the establishment and maintenance of an air quality surveillance system consisting of the air quality monitors in the state, is required to be submitted by all states to EPA. Specifically (a) requires for each existing and proposed monitoring site: 1. A statement of purpose for each monitor. 2. Evidence that siting and operation of each monitor meets the requirements of Appendices A, C, D, and E of 40 CFR Part 58, where applicable. 3. Proposals for any State and Local Air Monitoring Station (SLAMS) network modifications (b) requires the plan contain the following information for each existing and proposed site: a. The Air Quality System (AQS) site identification number. b. The location, including street address and geographical coordinates. c. The sampling and analysis method(s) for each measured parameter. d. The operating schedules for each monitor. e. Any proposals to remove or move a monitoring station within a period of 18 months following plan submittal. f. The monitoring objective and spatial scale of representativeness for each monitor. g. The identification of any sites that are suitable and sites that are not suitable for comparison against the annual PM2.5 NAAQS as described in h. The Metropolitan Statistical Area (MSA), Core Based Statistical Area (CBSA), Combined Statistical Area (CSA) or other area represented by the monitor. i. The designation of any Pb monitors as either source-oriented or non-sourceoriented according to Appendix D to 40 CFR part 58. j. Any source-oriented monitors for which a waiver has been requested or granted by the U.S. EPA Regional Administrator as allowed for under paragraph 4.5(a)(ii) of Appendix D to 40 CFR part 58. k. Any source-oriented or non-source-oriented site for which a waiver has been requested or granted by the U.S.EPA Regional Administrator for the use of Pb- PM10 monitoring in lieu of Pb-TSP monitoring as allowed for under paragraph 2.10 of Appendix C to 40 CFR part 58. l. The identification of required NO2 monitors as near-road, area-wide, or vulnerable and susceptible population monitors in accordance with Appendix D, section 4.3 of this part. m. The identification of any PM 2.5 FEMs and/or ARMs used in the monitoring agency s network where the data are not of sufficient quality such that data are not to be compared to the NAAQS. For required SLAMS where the agency identifies that the PM 2.5 Class III FEM or ARM does not produce data of sufficient quality for comparison to the NAAQS, the monitoring agency must ensure that an operating FRM or filter-based FEM meeting the sample frequency requirements described in or other Class III PM2.5 FEM or ARM with data of sufficient quality is operating and reporting data to meet the network design criteria described in appendix D to this part.

11 2017 Ambient Air Plan.docx 5/23/2017 Monitoring Requirements Appendix A of 40 CFR Part 58 outlines the Quality Assurance Requirements for SLAMS, SPMs, and PSD Air Monitoring. It details calibration and auditing procedures used to collect valid air quality data, the minimum number of collocated monitoring sites, calculations used for data quality assessments, and reporting requirements. All sites in Alabama operate following the requirements set forth Appendix A. Appendix C of 40 CFR Part 58 specifies the criteria pollutant monitoring methods which must be used in SLAMS and NCore stations. All criteria pollutant monitoring in Alabama follow the methods specified in Appendix C. Appendix D of 40 CFR Part 58 specifies network design criteria for ambient air quality monitoring. The overall design criteria, the minimum number of sites for each parameter, the type of sites, the spatial scale of the sites, and the monitoring objectives of the sites are detailed. In designing the air monitoring network for Alabama, the requirements of Appendix D were followed. The specifics for each pollutant network are in their individual chapters. Appendix E of 40 CFR Part 58 specifies the placement of the monitoring probe, its spacing from obstructions and probe material. All monitors operated in Alabama were evaluated against Appendix E criteria. Population and CBSA Alabama has a 2016 population estimate of 4,863,300 of which 3,967,381 is located in the 13 MSAs listed in Table 2. Minimum monitoring requirements vary for each pollutant and can be based on a combination of factors such as population, the level of monitored pollutants, and Core Based Statistical Area boundaries as defined in the latest US Census information. The term "Core Based Statistical Area" (CBSA) is a collective term for both Metropolitan Statistical Areas (MSA) and Micropolitan Statistical Areas (µsa). Table 2 lists the CBSAs in Alabama along with county names included in that area, and the 2016 estimated population. The Metropolitan Statistical Areas followed by the Micropolitan Statistical Areas are listed from highest to lowest population. Page 11 of 215

14 2017 Ambient Air Plan.docx 5/23/2017 Types of Monitoring Stations PAMS Photochemical Assessment Monitoring Station: PAMS are established to obtain more comprehensive data in areas with high levels of ozone pollution by also monitoring oxides of Nitrogen (NOx) and volatile organic compounds (VOCs). PAMS monitoring requirements were revised in the 2016 ozone NAAQS rule and a PAMS site will be required in the state of Alabama in Jefferson County. This site will need to be operational by SLAMS - State or Local Ambient Monitoring Station: The SLAMS make up ambient air quality monitoring sites that are primarily needed for NAAQS comparisons. Alabama SLAMS are described in detail by pollutant and monitoring agency in the section labeled Alabama s SLAMS by Pollutant. STN PM2.5 Speciation Trends Network: A PM2.5 speciation station designated to be part of the speciation trends network. This network provides chemical species data of fine particulates. There is currently one STN site located in Alabama at the North Birmingham NCore site ( ) operated by JCDH. Supplemental Speciation - Any PM2.5 speciation station that is used to gain supplemental data and is not dedicated as part of the speciation trends network. Two PM 2.5 supplemental speciation sites are located in Alabama: Phenix City-Girard School (AQS ID ) operated by ADEM and Wylam (AQS ID ) operated by JCDH. NCore National Core multi-pollutant monitoring station: Sites that measure multiple pollutants at trace levels in order to provide support to integrated air quality management data needs. Each state is required to operate one NCore site. The NCore site for Alabama is at the North Birmingham site (AQS ID ), Birmingham-Hoover MSA, operated by JCDH. Additional information concerning this site can be found in the JCDH Air Monitoring Network Description. CASTNET Clean Air Status and Trends Network: is a national air quality monitoring network designed to provide data to assess trends in air quality, atmospheric deposition, and ecological effects due to changes in air pollutant emissions. CASTNET provides long-term monitoring of air quality in rural areas to determine trends in regional atmospheric nitrogen, sulfur, and ozone concentrations and deposition fluxes of sulfur and nitrogen pollutants in order to evaluate the effectiveness of national and regional air pollution control programs. EPA-sponsored CASTNET ozone monitors are Part 58 compliant, therefore the data can be used for regulatory purposes. CASTNET Ozone data is now reported to AQS. There is one CASNET site in Alabama, Sand Mountain in DeKalb County (AQS ID ), operated by an EPA contractor. SO2 Data Requirements Rule (DRR) Effective September 21, 2015, per 40 CFR Part 51, states are required to report all sources that generate >2,000 tpy SO2, not dependent upon population density. Each source in this category must characterize air quality through air quality modeling or ambient air monitoring. Each source that chooses monitoring must operate their site equivalent with the SLAMS requirements of 40 CFR Part 58. Source-oriented monitoring for SO2 is required from January 1, 2017 through December 31, 2019 for adequate data to calculate a valid design value. Alabama has one DRR SO2 monitoring site, Lhoist (AQS ID ) operated by a contractor. Page 14 of 215

15 2017 Ambient Air Plan.docx 5/23/2017 Alabama s SLAMS by Pollutant Lead Network In 2008, EPA revised the NAAQS for lead (Pb). The Pb standard was lowered from 1.5 ug/m 3 for a quarterly average to 0.15 ug/m 3 based on the highest rolling 3-month average over a 3-year period. EPA set minimum monitoring requirements for source and population oriented monitoring. Source oriented monitoring is required near sources that have Pb emissions 1 ton per year. Population oriented monitoring is required for CBSAs >500,000. In December 2010, EPA revised the Pb rule to require source-oriented monitors for sources greater than ½ ton per year and stated that population oriented monitors would be located at NCore sites. In March, 2016, EPA removed the requirement for Pb monitoring at NCore sites that were not located near a Pb emissions source. Based on current emissions data or modeling, ADEM has identified one source, Sanders Lead Co., located in Troy, Pike County (not within a CBSA), which emits greater than 1/2 ton of Pb per year. Troy (AQS ID ), operated by ADEM, has been monitoring for Pb near that source since To meet QA requirements, collocated lead monitoring is also occurring at this site. Based on current emissions data, JCDH and the HDNREM have no sources that would require Pb monitoring. Based on population requirements, North Birmingham NCore site, Birmingham-Hoover MSA (AQS ID ),operated by JDCH, has been collecting Pb monitoring data since JCDH discontinued Pb monitoring at the North Birmingham NCore site at the end of calendar year No additional changes are proposed for this network. Page 15 of 215

16 2017 Ambient Air Plan.docx 5/23/2017 Carbon Monoxide (CO) Network On August 12, 2011 EPA issued a final rule that retained the existing NAAQS for Carbon Monoxide (CO) and made changes to the ambient air monitoring requirements. EPA revised the minimum requirements for CO monitoring by requiring CO monitors to be sited near roads in certain urban areas. 40 CFR Part 58 Appendix D, 4.2 details the requirements for CO monitoring General Requirements. (a) Except as provided in subsection (b), one CO monitor is required to operate collocated with one required near-road NO2 monitor, as required in Section of this part, in CBSAs having a population of 1,000,000 or more persons. If a CBSA has more than one required near-road NO2 monitor, only one CO monitor is required to be collocated with a nearroad NO2 monitor within that CBSA. (b) If a state provides quantitative evidence demonstrating that peak ambient CO concentrations would occur in a near-road location which meets microscale siting criteria in Appendix E of this part but is not a near-road NO2 monitoring site, then the EPA Regional Administrator may approve a request by a state to use such an alternate near-road location for a CO monitor in place of collocating a monitor at near-road NO2 monitoring site. Those monitors required in CBSAs having 1 million or more persons were required to be operational by January 1, Based on this, the requirement for a CO monitor to be collocated with the near road NO2 monitor in the Birmingham-Hoover CBSA and operational by January 1, 2017 is satisfied at the Near Road Arkadelphia Site (AQS ID ), operated by JCDH. Currently CO is monitored at the following sites : Table 3 JCDH CO Monitoring Sites AQS No. County Site Name Latitude Longitude Start Date Objective Scale Frequency Jefferson N.

17 2017 Ambient Air Plan.docx 5/23/2017 Nitrogen Dioxide (NO2) Network On January 22, 2010 the US EPA finalized the monitoring rules for Nitrogen Dioxide (NO2). The new rules include new requirements for the placement of new NO2 monitors in urban areas. These include: Near Road Monitoring At least one monitor must be located near a major road in each CBSA with a population 500,000 people. A second monitor is required near another major road in areas with either a CBSA population 2.5 million people, or one or more road segment with an annual average daily traffic (AADT) count 250,000 vehicles. These NO2 monitors must be placed near those road segments ranked with the highest traffic levels by AADT, with consideration given to fleet mix, congestion patterns, terrain, geographic location, and meteorology in identifying locations where the peak concentrations of NO2 are expected to occur. Monitors must be placed no more than 50 meters (about 164 feet) away from the edge of the nearest traffic lane. For near road NO2 monitoring, Birmingham-Hoover is the only CBSA in Alabama with a population greater than 500,000. However, the population is less than 2.5 million and there are no road segments with AADT greater than 250,000 vehicles. Therefore, only one near road NO2 monitor is located in the Birmingham-Hoover CBSA. JCDH has established a site at Arkadelphia Road known as Near Road Site (AQS ID ), that monitors for NO2, CO and PM2.5. The establishment of a permanent near-road NO2 monitoring site meeting design and siting criteria as specified in 40 CFR Part 58 was operational on January 1, Community Wide Monitoring A minimum of one monitor must be placed in any urban area with a population greater than or equal to 1 million people to assess community-wide concentrations. For community wide monitoring, Birmingham-Hoover is the only CBSA in Alabama with a population greater than 1 million, thereby requiring one NO2 monitor. North Birmingham NCore (AQS ID ), operated by JCDH, monitors for NOy and NO2 based on community wide requirements. No changes are proposed for this network. Page 17 of 215

18 2017 Ambient Air Plan.docx 5/23/2017 Sulfur Dioxide (SO2) Network Effective August 23, 2010, EPA strengthened the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). EPA established a new 1-hour standard at a level of 75 parts per billion (ppb), based on the 3-year average of the annual 99th percentile of 1-hour daily maximum concentrations.. According to EPA, for a short-term 1-hour SO2 standard, it is more technically appropriate, efficient, and effective to use modeling as the principal means of assessing compliance for medium to larger sources, and to rely more on monitoring for groups of smaller sources and sources not as conducive to modeling. Such an approach is consistent with EPA s historical approach and longstanding guidance for SO2. EPA is setting specific minimum requirements that inform states on where they are required to place SO2 monitors. The final monitoring regulations require monitors to be placed in Core Based Statistical Areas (CBSAs) based on a Population Weighted Emissions Index (PWEI) for the area. The final rule requires: 3 monitors in CBSAs with PWEI values of 1,000,000 or more; 2 monitors in CBSAs with PWEI values less than 1,000,000 but greater than 100,000; and 1 monitor in CBSAs with PWEI values greater than 5,000. According to the latest PWEI calculations listed in Table 4, only the Birmingham-Hoover and Mobile CBSAs require SO2 monitoring. The Birmingham-Hoover CBSA requires one SO2 monitor. North Birmingham NCore (AQS ID ) and Fairfield (AQS ID ), operated by JCDH, monitor for SO2 to fulfill the requirement. The Mobile CBSA requires one SO2 monitor. Chickasaw (AQS ID ), operated by ADEM since 01/01/2013, monitors for SO2 to fulfill the requirement. Effective September 21, 2015, per 40 CFR Part 51, states are required to report all sources that generate >2,000 tpy SO2, not dependent upon population density. For each source in this category, air quality must be determined through air quality modeling or ambient air monitoring. For sources that are characterized by monitoring operation of the site must be equivalent with the SLAMS requirements of 40 CFR Part 58. Lhoist North America of Alabama, LLC Montevallo Plant, (AQS ID ) located in Calera, Birmingham-Hoover MSA will be characterized by monitoring. Monitoring began on January 1, ADEM plans to begin monitoring SO2 at the Ward site in Sumter County (AQS ID ) as a background site beginning in January The monitor will be designated as a Special Purpose Monitor (SPM). No other changes are planned for this network. Page 18 of 215

20 2017 Ambient Air Plan.docx 5/23/2017 PM10 Network PM10 has been a criteria pollutant since Since that time there has been widespread monitoring of the PM10 levels in Alabama. In 2006 the US EPA modified the NAAQS for PM10 to revoke the annual standard. Currently, there is still a daily standard of 150 ug/m 3 based on 3 years of data. All monitors in the state have recorded PM10 levels that meet the NAAQS. Table 5 shows the minimum monitoring requirements. Table 5 Appendix D to Part 58. PM 10 Minimum Monitoring Requirements TABLE D 4 OF APPENDIX D TO PART 58. PM10 MINIMUM MONITORING REQUIREMENTS (NUMBER OF STATIONS PER MSA) 1 Population category High concentration 2 Medium concentration 3 Low concentration 4,5 >1,000, ,000 1,000, , , , , Selection of urban areas and actual numbers of stations per area within the ranges shown in this table will be jointly determined by EPA and the State Agency. 2 High concentration areas are those for which ambient PM10 data show ambient concentrations exceeding the PM10 NAAQS by 20 percent or more. 3 Medium concentration areas are those for which ambient PM10 data show ambient concentrations exceeding 80 percent of the PM10 NAAQS. 4 Low concentration areas are those for which ambient PM10 data show ambient concentrations less than 80 percent of the PM10 NAAQS. 5 These minimum monitoring requirements apply in the absence of a design value. The Birmingham-Hoover MSA has a population >1,000,000 and PM10 concentrations 80 percent of the PM10 National Ambient Air Quality Standards (NAAQS). According to Table 5 above, the Birmingham-Hoover MSA is required to operate between 4 and 8 PM10 monitoring sites. Due to historically low PM10 concentrations and lower populations in Walker, Shelby, and Chilton Counties, these required sites are located in Jefferson County and operated by JCDH where the population and emissions are primarily concentrated. Currently, JCDH operates PM 10 monitors at five sites which are acceptable for comparison to the NAAQS. The North Birmingham NCore site (AQS ID ) has three PM10 monitors: the primary monitor on a 1 in 3 day schedule, a collocated monitor on a 1 in 6 day schedule and one continuous monitor. The Leeds Elementary School site (AQS ID ) has one PM10 monitor on a 1 in 6 day schedule. The Wylam site (AQS ID ) has three PM10 monitors: a primary and collocated low volume monitor on a 1 in 6 day schedule, and a continuous monitor. JCDH is proposing to discontinue operation of all low volume PM10 monitors at this site. The Tarrant Elementary School site (AQS ID ) has one continuous PM10 monitors. A low volume PM10 monitor was discontinued at the end of The Sloss Shuttlesworth site (AQS ID ) has one continuous PM10 monitor. Page 20 of 215

21 2017 Ambient Air Plan.docx 5/23/2017 According to Table 5, Columbus, GA-AL, Huntsville, Mobile and Montgomery MSAs,with populations between 250,000 and 500,000 and concentrations less than 80% of the NAAQS, are required to have 0 to 1 monitors. In the Huntsville MSA, HDNREM operates high volume PM10 monitors on a 1 in 6 day schedule, which are comparable to the NAAQS, at each of the following sites: Pulaski Pike-Fire St. #10 (AQS ID ), South Parkway-Fire St. #7 (AQS ID ) and Huntsville Old Airport Road (AQS ID ). The Huntsville Old Airport Road site (AQS ID ) is also the location of a continuous hi-volume PM10 monitor. Additionally, a special purpose hi-volume PM10 monitor is located at the Downtown Garage Site (AQS ID ) for daily reporting to the public only, not for NAAQS comparison. In the Montgomery MSA, ADEM operates two high volume PM10 monitors on a 1 in 6 day schedule at the MOMS site (AQS ID ), one of them being the collocated quality assurance monitor. No changes are proposed in this MSA. Page 21 of 215

22 2017 Ambient Air Plan.docx 5/23/2017 Ozone Network Effective December 28, 2015, the level of the NAAQS for ozone was changed from to ppm. To attain this standard, the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations measured at each monitor within an area over each year must not exceed ppm.. Minimum monitoring requirements for ozone are based on population and whether the design value is <85% of the NAAQS, or 85% of the NAAQS (See Table 6). Since the NAAQS for ozone is parts per million of ozone then 85% of the NAAQS truncated is ppm Table 6 Appendix D To Part 58.

There are currently two Ozone sites, MOMS (AQS ID: ) and Wetumpka (AQS ID: ), operated by ADEM. The Wetumpka, DBT (AQS ID: ) closed on 06/27/2016 and the new ozone monitoring site, Wetumpka (AQS ID: ) began operating on 03/17/2017. Tuscaloosa MSA Using the Tuscaloosa MSA population estimate in 2016 (Table 2) and the design value from Table 7, one Ozone monitor is required for this MSA. There is currently one Ozone site, Duncanville (AQS ID: ), operated by ADEM. No changes are planned for this MSA. Auburn-Opelika and Anniston-Oxford MSAs The MSAs of Auburn-Opelika and Anniston-Oxford were evaluated by ADEM. Both MSAs have populations less than 160,000. It was determined that due to the close proximity of ozone monitors in the neighboring MSAs, additional ozone monitors would not be needed. Since these areas do not have design values, no Ozone monitors are required by Appendix D of 40 CFR 58. Sites not located in an MSA Sumter County represents rural, background ozone values for the state. The historical design values for this monitor have been less than 85% of the NAAQS. One Ozone site, Ward (AQS ID: ), operated by ADEM, is located in Sumter County. No changes are planned for this site. There is an Ozone monitor, located at the CASTNET site near Crossville in DeKalb County, Sand Mountain (AQS ID: ), operated by EPA. Page 25 of 215

26 2017 Ambient Air Plan.docx 5/23/2017 PM2.5 Network Minimum monitoring requirements for PM2.5 are based on population and whether the design value is less than 85% of the NAAQS, or greater than or equal to 85% of the NAAQS (See Table 8). In addition to the FRM monitors required by Table 8, the state is required to operate a regional background and a regional transport site. Section of Appendix D of 40 CFR Part 58 also requires a collocated continuous PM2.5 monitor in each MSA that is required to have a FRM monitor. The number of collocated continuous monitors required for an MSA will be equal to at least half of the required FRM monitors for that MSA. This requirement goes away if the continuous monitor is a FEM that is labeled as the primary and comparable to the NAAQS. The state is also required to operate PM2.5 speciation monitors to characterize the constituents of PM2.5. The number of speciation monitors is determined in consultation with EPA Region IV. PM2.5 design values in Table 9 are based on data. A design value of ug/m 3 is the lowest value which is 85% of the 24-hour standard of 35 ug/m 3. A design value of 10.2 ug/m 3 is the lowest value that is 85% of the annual standard of 12 ug/m 3 (effective March 18, 2013). Table 8 Appendix D To Part 58, PM2.5 Minimum Monitoring Requirements TABLE D 5 OF APPENDIX D TO PART 58 PM2.5 MINIMUM MONITORING REQUIREMENTS MSA population 1,2 Most recent 3-year design value 85% of any PM2.5 NAAQS 3 Most recent 3-year design value<85% of any PM2.5 NAAQS 3,4 >1,000, ,000 1,000, ,000 <500, Minimum monitoring requirements apply to the Metropolitan statistical area (MSA). 2 Population based on latest available census figures. 3 The PM2.5 National Ambient Air Quality Standards (NAAQS) levels and forms are defined in 40 CFR part These minimum monitoring requirements apply in the absence of a design value. 5 Metropolitan statistical areas (MSA) must contain an urbanized area of 50,000 or more population. The current PM2.5 Rule requires CBSAs with populations greater than a million but less than 4 million operate a PM2.5 monitor at its NO2 near road site by January 1, The only CBSA in Alabama that requires a NO2 near road monitoring site is the Birmingham-Hoover MSA. The requirement is satisfied by Near Road Arkadelphia Site (AQS ID ), operated by JCDH. In order to meet the continuous monitoring requirements of Appendix D, ADEM currently operates seven MetOne BAM monitors (AQS method code 731) which do not have FEM designation. These monitors are also used for AQI reporting and for submittal to the AirNow system. Comparison with the NAAQS will be based on the FRMs at each site which are designated as the primary monitor and operate on the required frequency. Table 9 lists Alabama s PM2.5 sites, AQS ID, the PM hour and Annual and Design Values for each site, MSA name, the 2016 estimated population of the MSAs, the Annual and 24- hour Design Value for each MSA, number of monitors required by the CFR and the current number of PM2.5 monitors.

There is currently one FRM monitor and one non-fem continuous monitor located at the VA, Tuscaloosa site (AQS ID: ). No changes are planned for this MSA. Auburn-Opelika and Anniston-Oxford MSAs The MSAs of Auburn-Opelika and Anniston-Oxford were evaluated to determine the need for monitors. Both MSAs have populations less than 160,000. It was determined that due to the close proximity of PM2.5 monitors in neighboring MSAs, additional monitors would not be needed. PM2.5 monitoring in the adjacent MSAs continue to provide adequate coverage. Since these areas do not have design values, no FRM monitors are required by Appendix D of 40 CFR Part 58. PM2.5 Monitors not located in MSAs Sumter County represents rural, background PM2.5 values for the west part of the state. ADEM operated an FRM monitor in Sumter County until A non-fem continuous monitor is currently being operated in Ward, Sumter County (AQS ID: ). ADEM intends to maintain this site. The Micropolitan Statistical Area of Talladega-Sylacauga is adjacent to the Anniston-Oxford and the Birmingham-Hoover MSAs. There is currently one FRM monitor located in Childersburg, Talladega County (AQS ID: ). The PM2.5 design value from Table 9 is less than 85% of the NAAQS for this monitor. ADEM proposes to close this PM2.5 monitor due to its low design value and since it is not in an MSA. This site is not required by 40 CFR 58, Appendix D. The annual design values for the past five year are in Table 10 below. Table 10 Childersburg Annual Design Values Annual hour An FRM monitor located near Ashland, Clay County (AQS ID: ), serves as a regional transport site in between the large MSAs of Birmingham-Hoover and Atlanta.

31 2017 Ambient Air Plan.docx 5/23/2017 Quality Assurance Each of the three monitoring agencies have US EPA approved Quality Assurance Program Plans that detail the activities used to control and document the quality of the data collected. Each agency operates as an independent Primary Quality Assurance Organization (PQAO) as defined by 40 CFR Part 58. Part of the EPA required quality control program for particulate monitors is the use of collocated particulate monitors. 40 CFR Part 58, Appendix A requires a percentage of manual particulate monitors to be collocated with FRM monitors so that quality statistics can be calculated. Each agency network includes monitors for this purpose. Monitoring Equipment Evaluation An evaluation of the condition of ambient monitors and auxiliary equipment was performed by each of the three monitoring agencies. The equipment was categorized as good or poor. As resources allow, equipment in poor condition will be replaced. A report of each Agency s equipment evaluation will be submitted to the US EPA by July 1 each year. Page 31 of 215

43 2017 Ambient Air Plan.docx 5/23/2017 APPENDIX A Jefferson County Department Of Health (JCDH) Annual Air Monitoring Network Plan May 2017 Regulations codified at 40 CFR Part 58, Appendices D (Network Design Criteria for Ambient Air Quality Monitoring) and E (Probe and Monitoring Path Siting Criteria for Ambient Air Quality Monitoring) were reviewed to determine if modifications to the existing air monitoring network are required. Summary of JCDH Network Review Lead (Pb) monitoring is required in major urbanized areas where Pb levels have been shown or are expected to be of concern due to the proximity of Pb point source emissions. According to the new lead regulations, sources emitting a half ton or more of lead per year would be candidates for lead ambient air monitoring. There are no longer any significant point sources of lead emissions greater than the half ton threshold in Jefferson County. Therefore, based on past monitoring and 2015 emissions inventory data, a lead source monitoring site is not required. The EPA revised the NAAQS for Nitrogen Dioxide and it was promulgated in February In this rule, EPA required changes to the monitoring network that will focus monitoring resources to capture short-term NO2 concentrations near heavily trafficked roads, to assess area-wide (or community-wide) NO2 concentrations, and to assess NO2 concentrations for vulnerable and susceptible populations. Jefferson County has installed the requisite monitoring site in October 2013 which became operational on January 1, NOy monitoring began at the NCore site January 1, To determine localized concentrations of PM2.5 in the North Birmingham area, the Department conducted PM2.5 monitoring at the Shuttlesworth site for one year [from July 1, 2013 to September 30, 2014]. This was operated as a special purpose, non-slams monitor. Concentrations and concentration variations were very similar to those at next closest, proximate site, the North Birmingham monitoring site. JCDH will continue to monitor for PM2.5 at this site using a continuous monitoring method where the results will be publically accessible through the AirNow website located in the JCDH webpage. Continuous PM2.5 SPM (Special Purpose Monitors) Continuous PM2.5 monitoring is required in relation to the minimum SLAMS monitoring requirement stated above; i.e., equal to at least one-half (round up) the minimum monitoring requirement. Jefferson County is required to operate two continuous PM2.5 monitors. However, seven continuous PM2.5 monitors are actually operated in Jefferson County for the purpose of AirNow mapping and six to support our Birmingham Air Quality website. Continuous PM2.5 monitors are collocated with manual PM2.5 monitors at North Birmingham, Wylam, McAdory and Leeds for quality assurance purposes. Continuous SO2 SPM (Special Purpose Monitors) The Department established an SO2 analyzer at the Shuttlesworth monitoring site. Page 43 of 215

44 2017 Ambient Air Plan.docx 5/23/2017 The analyzer will be operated for one (1) year, after which time the data will be reviewed. If the data show consistent exceedances of the SO2 standards, the analyzer would be operated a full three (3) years to obtain a design value. Network Review Findings The existing network as summarized in the attached Air Monitoring Network Description complies with 40 CFR Part 58 requirements. The described network should adequately characterize typical population exposure concentrations and compliance status with the NAAQS for pollutants of concern. The monitoring site location map can be found in APPENDIX D. Page 44 of 215

45 2017 Ambient Air Plan.docx 5/23/2017 APPENDIX B Huntsville Department of Natural Resources and Environmental Management (HDNREM) Annual Air Monitoring Network Plan April 25, 2017 Regulations codified at 40 CFR Part 58, Appendices A (Quality Assurance Requirements for SLAMS, SPMs and PSD Air Monitoring), C (Ambient Air Quality Monitoring Methodology), D (Network Design Criteria for Ambient Air Quality Monitoring) and E (Probe and Monitoring Path Siting Criteria for Ambient Air Quality Monitoring) were reviewed to determine if modifications to the existing air monitoring network are required. NCore Ambient Air Monitoring Stations Each State is required to operate one NCore site (multipollutant). Huntsville was not selected for the NCore site. PAMS (Photochemical Assessment Monitoring Stations) PAMS monitoring is required in areas classified as serious, severe, or extreme for the 8-hour ozone standard. Huntsville is presently classified as an ozone attainment area. Consequently, PAMS monitoring is not required. SLAMS (State and Local Air Monitoring Stations) The minimum ozone monitoring requirements are based on MSA (Metropolitan Statistical Area) populations and 3-year design value concentrations. The Huntsville MSA population is 417,593 based on the 2010 decennial census population. Huntsville s 3-year design value concentration for is.064 ppm. MSA s with populations of 50,000 to less than 350,000 having a design value >85% of the O3 NAAQS are required to operate one ozone site. MSA s with populations of 350,000 to less than 4,000,000 are required to operate two ozone sites. Huntsville operates two ozone monitoring sites, as required. There is a two-tier minimum nitrogen dioxide (NO2) monitoring requirement. Near-road microscale monitoring is required in each CBSA (Core-based statistical area) with a population of 1,000,000 or more. Area-wide high concentration monitoring is required in each CBSA with a population of 1,000,000 or more. The Huntsville CBSA population is 417,593. Huntsville is not required to operate a SLAMS NO2 monitor. The minimum monitoring requirements for carbon monoxide (CO) require one monitor be collocated with a near-road NO2 monitor in each CBSA with a population of 1,000,000 or more. Huntsville is not required to operate a SLAMS CO monitor. The minimum sulfur dioxide (SO2) monitoring requirements are based on a Population Weighted Emissions Index (PWEI), which is calculated by multiplying the population of the CBSA and the total SO2 emissions (using the most recent published version of the National Emissions Page 45 of 215

46 2017 Ambient Air Plan.docx 5/23/2017 Inventory (NEI)) within the CBSA area. The resulting product is then divided by one million, representing million persons-tons per year. Areas having a PWEI greater than 1,000,000 are required to operate 3 monitors; areas having a PWEI equal to or greater than 100,000 but less than 1,000,000 are required to operate 2 monitors; areas having a PWEI greater than 5,000 but less than 100,000 are required to operate 1 monitor. The Huntsville PWEI is 153 (based on 2010 decennial census population and 2014 NEI, total SO2 emissions data for the Huntsville CBSA). Huntsville is not required to operate a SLAMS SO2 monitor. Lead monitoring (Pb) is required in areas where Pb levels have been shown or are expected to be of concern due to the proximity of Pb point source emissions. Generally, industrial sources emitting 0.5 ton or more of lead per year and airports emitting 1.0 ton or more per year would be candidates for lead ambient air monitoring. There are no significant point sources of lead emissions in Huntsville. Based on past monitoring and emissions inventory data, a SLAMS lead site is not required. Huntsville s PM10 concentrations are less than 80 percent of the PM10 NAAQS (National Ambient Air Quality Standards). Based on Huntsville s MSA population being between 250, ,000 and low concentrations, Huntsville is required to operate 1 site. Huntsville operates 3 PM10 sites located in south, central, and north Huntsville. These monitors can be operated at very low cost and provide good spatial coverage within the city. Experience has shown that members of the public want ambient air monitoring to be performed in their part of the city, and the PM10 monitoring sites provide a monitoring presence at relatively low cost. Furthermore, the PM10 data provide an indirect indication of PM2.5 spatial variability at a tiny fraction of the cost of operating multiple PM2.5 sites. The minimum PM2.5 monitoring requirements are based on MSA populations and 3-year design value concentrations. Huntsville s 3-year design value concentration for is 17.0 µg/m3 for the 24-hour standard and 8.2 µg/m 3 for the annual standard. MSA s with populations of 50,000 to less than 500,000 having a design value 85% of the PM2.5 NAAQS are required to operate one PM2.5 site on a 1 in 3 day sampling frequency. Huntsville operates one PM2.5 site on a 1 in 3 day schedule although the current design values are <85% of the NAAQS. Note: Operating frequency increases to daily sampling when the 24-hour design value is within ± 5 percent of the 24-hour PM2.5 NAAQS (34, 35, and 36 µg/m 3 ). SLAMS sites were also evaluated to determine consistency of spatial scales with stated monitoring objectives. Reference the attached monitoring network description. In addition to the information listed below, the description also indicates site locations, monitoring methodologies, and operational schedules. Page 46 of 215
